The force represents the crushing strength of the tablet, which is cylindrical with flat faces, having dia. 13 mm, thickness 5 mm and wt. 0.896 g, i.e. apparent density 1.35g/ml. The force is applied against the peripheral surface of the tablet in the direction of the axis of the revolution using a movable support applied against the surface along a generatrix. The tablet is additionally held against a fixed support, also applied against the surface of the tablet along a generatix diametrically opposed to that to which the mobile support is applied.
